][+ Video card question(s)

[gerome@teleport.com (Gerome Manufacturing)]

Hi!

	I just picked up a II+ for 20$ today, and it has an 80 column card
in it made by videx.  I found that using escape+ one of the number keys
would change through various text modes ranging from 80x24 to 160x24.  There
are a number of connectors and jumpers and dip switches on this thing.  Does
anyone have some information describing what they do?

	There is a wire connecting from somewhere around the game port to
somewhere near the keyboard.  (sorry I am at work and don't know the exact
pins & chips...)  A friend told me that was the double hi-res hack, and that
a person can get the II+ to do it, if a wire connected two points in the
computer.  In my case, there is one end not connected.  Does anyone know
what this mod. could do?  

	Thanks in advance.
